I have some questions about Fire Safety?

1. Describe how specific gravity affects combustion and extinguishment?
2. Describe why water is a poor extinguishing agent for most flammable and combustible liquids?
3. How is the specific gravity of gasoline, motor oil, and kerosene in relationship to water?
4. Why will kerosene not burn easily when it’s at room temperature?
5. Why does an alcohol fire go out with water and the gasoline fire did not?
6. Why will gasoline burn easily when it is at room temperature?
7. Why did the flame extinguish when it contacted the paper clip?

I need to store about 50/100 gallons of gasoline for winter (generator-emergencies etc) How?

I want it to be safe of course and probably above ground (for gravity flow) to fill jugs. I heard storing gasoline for a long time tends to collect water or condensation in it somehow. I don’t want water in my gas! Also, does it need to be vented or sealed off tightly? Ever heard of lightening striking a gas storage tank ? I need to know ALL the best advice and safe solutions to do this. Thanks! Teri

I have a question about price controls. . .?

This is for my class and I am so very confused. Can someone help me answer this?

When oxygen gas and hydrogen gas combine, they form water. What does this indicate about the properties of new compounds that are formed from different elements?

Can I improve my gas milage by filling my tires with helium? How about Hydrogen?

Any And EVERYONE Who Knows Anything About Cars Starting. Speak Your Minds… Out of Ideas. 1972 Chevelle 350?

This car is driving me insane getting it started. Granted, I have knowledge of motors and cars but I can’t seem to figure out what my friends and I are doing wrong. Ok with this car, we have been replacing parts left and right. It has sat for over 10 years but a couple months ago, we started replacing a lot. Here is the list: Starter, battery, alternator, distributor, spark plugs, spark plug wires, head gaskets, thermostat, intake manifold gaskets, hoses, belts, cables, water pump, air filter, fuel filter, fuel lines, fuel pump, installed new fresh fuel draining all the old fuel out. Adjusted the valves four times (we know they are good), checked timing way too many times and that is good and probably some other parts I am forgetting. Anyway, I bought a rebuilt Rochester 2GV carb from a guy with the same exact car as mine (1972 chevelle 350 A/T 2 barrel carb.) He said he ran it on his car and it worked fine. Installed it on mine and the car improved. When I go to start it, it turns over extremely well and gets really really REALLY close to starting but won’t go over the hill to say the least. Itll go vr-vr-vr-vr-vr-vr-vr-vr-VR-VR-VR-(and just about ready to vroooooooooooom) but it won’t do that. Just turns over really fast but won’t go fully and start and idle. With these cars, it should “mumble” or hear the muscle car sound when idling or turning over for that matter. But when we turn it over, sometimes you can hear the muscle car sound but others, all you hear is just regular turning over like a regular toyota or other import car. Not picking on them, but you cant hear the muscle car sound when my car is turning over. Sometimes you can, others, nothing. About 50/50. So anyway, I look down inside the carb. If you move the throttle cable back and fourth, you can see the accelerator pump pumping. See the fuel squirting. Sprayed starting fluid in there, and nothing happened. Just turning over regularly. I know sometimes before, you can actually hear it take affect when sprayed in there. It’ll actually start and then stall right away. But today, it wouldn’t take no affect. Checked timing light, and the timing is correct. So then, we took the fuel line off at the carb and turned it over, and there was only a lil’ bit of fuel coming out. It has gas but not a lot of fuel was spitting out. Hmm….? Like I said, when I hold the gas pedal down, it’ll get really close but just won’t go over the hill and won’t even start with starting fluid dirctly in there.

I’ve got a VW Golf 4motion – mk 4, and i’ve noticed the water temperature sits at about 92-94*C. Problem?

Just wondering if this means there is a problem with the water cooler, fan, head gasket? Or is this ok? Also the EPC light is on for quite a bit of the time. Does this mean there is a problem? I have put both 95 and 98 octane fuel in so it may be for that reason. Thanks for answers

after out on the water trolling for several hours,my boat won’t come up to speed. only goes about 10 mph.?

I’m a 22 foot C.C. with a 225 Merc. newer model, I’v changed the lower case oil and it seemed ok. the one day out on the water several hours trolling , i started my way back home and thats when she’d only go about 10 mph full throttel with with about 2500 rpm. after shutting the engine off several times it finally kicked back in and I was able to resume regular speed. any Ideas? I’m thinking throttel cabel, lower case problems, clogged fuel line.

What is a car with great gas mileage (only have about $10,000-$12,000 to spend)?

Currently driving a 2000 Chevy Malibu LS with almost 157,000 miles on it. Have had phenomenal luck with it so far and plan to drive it until repairs get too expensive or it goes out for good (only major thing to go wrong is water pump wore out and needed to be replaced). Otherwise, I do all the routine maintenance on it.

However, I know at some point in time I’m going to need another car. With gas prices increasing, I need something real economical. I’m looking into a Chevy Aveo or something similar to get really, really good gas mileage. (I drive 60 miles to and from work each day on a highway, on cruise control).
